ASF Calcium Booster – Powder
Concentrated Calcium Supplement for Reef Aquariums
ASF Calcium Booster Powder is a high-purity calcium supplement designed to restore and maintain calcium levels found in natural seawater.
Calcium is a fundamental macro element required for skeletal growth and calcification in stony corals, clams, and coralline algae.
Insufficient calcium limits coral growth, while unstable supplementation can lead to imbalance with alkalinity and magnesium. Calcium Booster Powder allows precise, controlled calcium adjustment, ideal for reefs with high consumption.
The optimal calcium range is 400–450 ppm.
